Hallow Dear,
Any type of bleeding during any stage of
pregnancy is not a good sign, particularly brown bleeding. Brown bleeding suggests that the baby is not viable.
Since your all 4 urine pregnancy tests are positive, you are definitely pregnant. However, the occurrence of brown bleeding is suggesting that you may be having
missed abortion. Missed abortion is a condition where the baby inside the
uterus is non-viable, still it is retained in the uterus. In such cases, it may take 8-10 days for the pregnancy test to become negative. Hence, positive pregnancy test will not help to confirm the diagnosis of missed abortion;
ultrasonography will reveal the status of your pregnancy.
If it is missed abortion, you will have to undergo surgical evacuation of pregnancy to terminate the pregnancy. Delaying uterine evacuation may lead to the complications like
clotting disorder leading to excessive bleeding (DIC), infection, etc. which are very serious.
Please report to your Obstetrician to confirm the diagnosis and undergo the required management ASAP.
